hi,poss fault ,the water temp sensor,the sensor measures the temp of the water and adjusts the amount of fuel supplied ,if faulty will deliver too much or not enough. or when the car will not start remove fuel feed hose crank engine & see if fuel is being delivered if no fuel poss the fuel pump relay fault, don't forget if checking for fuel on a hot engine petrol ignites very easily. hope this of some help
